Sound speed = ultrasound speed?

AI Thread Summary
Ultrasound is a type of sound with a frequency beyond human hearing, but it travels at the same speed as other sound waves in air. The speed of sound is generally independent of frequency, although slight variations can occur under different conditions, such as low pressure. For most practical applications, including lab reports, this difference is negligible. Therefore, ultrasound speed in air can be considered identical to sound speed in air. Understanding these principles is essential for accurate scientific reporting.

Hi, I'm doing a lab report and I need to know if ultrasound speed in the air is the same of sound speed in the air.
Thank you

Ultrasound is just sound with a very high frequency such that we can't hear it. Therefore, yes, it is identical to any other form of sound, including its speed in air.

Lookes like boneh3ad is right: http://hyperphysics.phy-astr.gsu.edu/hbase/sound/souspe.html

Speed of sound is very nearly independent of frequency, but not quite, (see A B Wood, A Textbook of Sound (Bell, London, 1946))

For your purposes I doubt it would make a difference. However for low pressures it might.
 
Thank you very much ;)
 

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
